A high pressure watertube boiler (also spelled water-tube and water tube) is a type of boiler in which water circulates in tubes heated externally by the fire. Fuel is burned inside the furnace, creating hot gas which boils water in the steam-generating tubes.In smaller boilers, additional generating tubes are separate in the furnace, while larger utility boilers rely on the water-filled …Get Price
The water in the tube becomes more concentrated, increasing the potential for deposition of boiler water salts. In extreme cases, deposition becomes heavy enough to reduce circulation to a point at which premature steam-water separation occurs. When this happens in a furnace tube, failure due to overheating is rapid.Get Price
The boiler water then travels down the downcomers between the air casings to the water drum. As the water travels up the generating tubes, the water is heated to its boiling point by the radiant heat from the boiler's furnace. The steam/water mixture reenters the steam drum at 490 ' F. The water that did not turn to steam repeats the process.Get Price

The water tube boiler diagram is shown below, and these two drums are associated via two tubes such as downcomer and riser. At first, the water is supplied into the steam type drum with the help of a water pump. Whenever the fuel is burned, then hot gases will be generated that are permitted to supply in the shell part of the boiler.Get Price
